Title:
LITHIUM SECONDARY BATTERY
Document Type and Number:
Japanese Patent JPH09115547
Kind Code:
A
Abstract:
To make a film hardly formed, which interferes with discharge, and is poor in electron conductivity, over the surface of a negative electrode, and also make a charge and discharge efficiency high.
In this battery, manganese dioxide heat-treated at 330-430°C is employed as positive electrode active material, as solvent for non-aqueous electrolyte, mixed solution is used in which ethylene carbonate is mixed with 1,2-dimethoxyethane by a specified ratio, or ethylene carbonate is mixed with propylene carbonate by a specified ratio, or butylene carbonate is mixed with 1,2-dimetoxythane by a specified ratio, and as non-aqueous electrolyte, lithium trifluoro methane sulfonate or lithium hexafluorophosphate is used.
